the central opening 21 of they partition or plate 19, and surrounding said pin between the plate 22 and the underneath face of the plate or partition 19 is a small coiled or helical spring 25. This spring' is employed to return the valve to its'normal position by bearing u on the plate 22 and holding the tapered en 24 of the pin 23 out of the opening or port 9 of the valve. The plate 19 is simply em loyed to prevent the spring, 25 rom interiering with the opening 9, also for preventing a displacement of the spring upon the late 22, it being observedI by'referring to gig. 1 of the drawings that thisspring does not touch the plate 19 in its normal position. In operation the normal pressure of gas is vadapted to pass through the openings '18` into the compartment 6, around the plate .22, through the openings 21 of the plate 19, and upwardly throu h the opening 9. The normal pressure o as partially elevates the plate 22 the sma lest fractional part of an inch, and should the pressure for some unforeseen cause be decreased or lowered the plate 22 will recede, permitting a greater area of space to exist in the (pening 9 through which t e gas may pass. uring the operation of the valve,'should the gas-pressure increase, the plate 22 will be elevated, moving the rod 23 into the opening 9 to artially .close the same, the size` of this rod re ative to the opening 9 being such as to permit a sufficient quantity of gas to pass therethrough to at all ight, whether the gas intimes maintain a creases or decreases in pressure. The member 11 is slmply employed for properly positioning the plate 22 within the valve, and

this member isalways screwed into the valvebody as far as possible and is only removed when it 1s, necessar to replace some of the parts contained wit in the valve.

My improved regulat'or, which is automatically actuated by fluctuations in the gaspressure, is particularly adapted for use in connection with mantles, where it is a wellknown fact that if the gas-pressure increases the mantle is broken and cannot again be used. My im rovedv regulator tends to overcome the brea age of mantles by an increase in the gas-pressure, also prevent the burning gas from being extinguished by an increase of pressure in the as-supply, consequently pre- Venting the asp yxiation of ersons occupying the compartments in W 'ch the gas .is burning. From the construction of' my improved valve it will be observed that comparativelyfew parts are used and parts of the valve can be readilyremoved at ltracted end, sai

` tures formed therein, a standard, carrie ing said in between sai that theV movabley l accurate y made in order to obtain a sensi-A tive coperation of these arts with the gaspressure. It will be evi ent from the construction of the above valve that I yhave devised a safety-valve and regulator to be used in connection with gas burners or jets, and I do not care to confine myself to the specific use of the regulator or valve inconnecticn with gas, as it can be readily employed for other purposes, such as air.

It is thought from the foregoing that the construction, operation, and advantages of the herein-described gas-regulator will be apparent without further description, and Vvarious changes in the form, proportion, and minor details of construction may be made without departing from the s irit of the invention or sacrificing any `of t e advantages thereof.'

What I claim, and desire to secure by Letters Patent, is-'- 1. A gas-regulator of the character described consistinv of a casing having a concasing having a compartment formed therein, terminating in said contracted end, said end having an opening formed therein, a perforated partition mounted in said end, a member-adjustably secured in said casing, and having a screw-threaded recess, the end of said member having a r- V said member and extending upwardly into said compartment, a plate mounted u on said standard, a pin carried by said p ate and extending through said partition into the opening of said casin a spring surroundpartition and said stantially as described.

2. A gas-regulator of the character described consisting of a casing. having an opening formed therein, said casing'havmg a compartment formed therein, a perforated partition mounted in said compartment, a plate carried within said compartment, a pin carried by said plate and extending upwardly through said partition into said opening, means to normally hold said pin out of sald plate, su

opening, substantially as described.

In testimony whereof'I alix my signature 1n the presence of two witnesses. v
